My Dad's (Ron) question was targeted to the Vivat/Prestige from Wistmodel,
which are composite planes with sealed top hinging for the ailerons and
elevators.  A thin curved molded piece of fiberglass or carbon fiber
(fairing) is attached to the bottom LE of the control surface.  When the
control surface is at neutral, the fairing is hidden inside the wing/stab
(inside the hinge gap as it were), and as the control surface deflects "up",
the fairing rotates with the surface to maintain zero gap.  Very slick
design and execution.  Wistmodel has been doing this for 5+ years that I
know of.  No "shriek" when doing snaps as with most of the composite winged
models out there.

 

Regards,

 

Dave
